在go中封裝一個bash函式，用於執行bash命令
package main
import "os/exec"
// 執行bash命令，返回輸出以及執行後退出狀態碼
func Bash(cmd string) (out string, exitcode int) {
cmdobj := exec.Command("bash", "-c", cmd)
output, err := cmdobj.CombinedOutput()
if err != nil {
// Get the exitcode of the output
if ins, ok := err.(*exec.ExitError); ok {
out = string(output)
exitcode = ins.ExitCode()
return out, exitcode
}
}
return string(output), 0
}執行
func main() {
out, _ := utils.Bash("ifconfig")
fmt.Println(out)
}
